METHOD FOR CONFERRING ANTIMICROBIAL ACTIVITY TO A SUBSTRATE

In one embodiment, the invention relates to a method for rendering a non-metallic substrate stably antimicrobial. The method comprises: (a) contacting the substrate with an antimicrobial surfactant; (b) contacting the substrate with a polymeric binder; and (c) subjecting the substrate, surfactant, a...

Beschreibung
Zusammenfassung:	In one embodiment, the invention relates to a method for rendering a non-metallic substrate stably antimicrobial. The method comprises: (a) contacting the substrate with an antimicrobial surfactant; (b) contacting the substrate with a polymeric binder; and (c) subjecting the substrate, surfactant, and binder to conditions at which the substrate becomes stably antimicrobial. In another embodiment, the invention relates to a substrate into which an antimicrobial surfactant and a binder have penetrated. Dans un mode de réalisation, l'invention concerne un procédé pour rendre un substrat non métallique antimicrobien de manière stable. Le procédé comprend : (a) la mise en contact du substrat avec un tensio-actif antimicrobien ; (b) la mise en contact du substrat avec un liant polymère ; et (c) la soumission du substrat, du tensio-actif, et du liant à des conditions selon lesquelles le substrat devient antimicrobien de manière stable. Dans un autre mode de réalisation, l'invention concerne un substrat à l'intérieur duquel un tensio-actif antimicrobien et un liant ont pénétré.
